Moreover, users can customize the functions of the touch button 2 and operate the touch button 2 by means of touching, sliding, applying pressure, etc. For example, the touch button can be a capacitive touch button, which uses tactile feedback to simulate the feeling of pressing a traditional button or senses the length, strength, and magnitude of the user's pressing time through pressure sensing technology to trigger operation functions, so as to realize various adjustment, switch, setting, and switching functions such as mobile phone operation / control of the mute switch, volume control, voice recording, opening the camera, taking pictures, recording videos, or other quick operations; however, modern people take good care of their mobile phones. Users usually set a protective case to protect the mobile phone. In this way, even if the protective case is provided with an opening corresponding to the position of the touch button 2 of the mobile phone, due to the too thick thickness of the protective case, the position of the touch button 2 is deep and difficult to operate, which affects the convenience of the user's finger operation.

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited are not intended to limit the present utility model.

[0023] Please refer to Figures 2 to 5, A button of a mobile phone case. A mobile phone case 10 has a back plate 11 and a frame 12 surrounding the back plate 11. An accommodation space 13 for accommodating a mobile phone 1 is formed within the range of the frame 12. One edge of the mobile phone 1 has a touch button 2. The frame 12 of the mobile phone case 10 is provided with a key positioning hole 14 adapted to the shape of the touch button 2. An elastic extension ring piece 15 protrudes radially from the inner peripheral surface of the key positioning hole 14. On the side of the elastic extension ring piece 15 facing away from the touch button 2, there is an inclined surface 151 inclined from the outer edge to the center, forming the elastic extension ring piece 15 recessed from the outer surface of the mobile phone case 10; A sensing key 20 is provided in the key positioning hole 14 of the mobile phone case 10. The sensing key 20 includes: an induction conduction component 21 and a washer 22; wherein the induction conduction component 21 is configured to fit the shape of the key positioning hole 14, and the elastic extension ring piece 15 is adhered to the outer peripheral surface of the induction conduction component 21 to be integrally fixed, and one end of the induction conduction component 21 protrudes in the direction of the touch button 2, and the surface of the induction conduction component 21 facing away from the touch button 2 is flush with the side of the elastic extension ring piece 15 facing away from the touch button 2; A printing layer 23 is provided on the surface of the induction conduction component 21, and then a transparent covering piece 24 is provided on the printing layer 23, and the surface of the covering piece 24 does not protrude from the outer surface of the mobile phone case 10; A number of neatly arranged conduction parts 211 are arranged on the induction conduction component 21, and each of the conduction parts 211 exposes two opposite surfaces of the induction conduction component 21; And the washer 22 is a soft ring body. The washer 22 is arranged on the side of the elastic extension ring piece 15 facing the touch button 2, and the washer 22 is bonded to the outer peripheral edge of the induction conduction component 21 integrally, and the washer 22 is respectively abutted between the periphery of the touch button 2 of the mobile phone 1 and the elastic extension ring piece 15, and the induction conduction component 21 corresponds to the touch button 2; By the user touching or applying pressure to the sensing key 20 with a finger 3, the touch button 2 receives a touch or pressure signal, and the mobile phone 1 generates corresponding setting actions and functions, achieving the effect of easily controlling the touch button 2.

[0024] The composition, function, and details of the above embodiment are described as follows: As Figures 2 to 5As shown, the elastic extension ring piece 15 of the present utility model is a thin sheet ring integrally protruding from the protective shell 10, and has the same material as the protective shell 10, which is made of soft elastic materials including but not limited to silicone, rubber, and plastic, so that it can be elastically deformed by an external force and restore its shape when the external force is removed; the combination of the elastic extension ring piece 15 and the induction conduction component 21 can be achieved by bonding or overmolding to combine the two. The printing layer 23 can be coated or printed with decorative colors, patterns, graphics, lines, or reticulations according to the user's needs, making the sensing key 20 more diverse; the material of the covering piece 24 includes but not limited to transparent materials such as sapphire, glass, and plastic sheets, and can transmit the patterns of the printing layer 23. The conduction part 211 of the induction conduction component 21 can conduct the current of the finger 3, and its material includes but not limited to conductive metal materials, chemical metal composite materials, or semiconductor materials, etc. When the finger 3 touches the covering piece 24, the touch signal can be conducted through the covering piece 24 and the printing layer 23 to the conduction part 211, and the conduction part 211 transmits the touch signal to the touch button 2. At this time, the controller of the touch button 2 will calculate the position of the finger 3 and the function represented by that position based on the difference in current changes; furthermore, the gasket 22 is made of soft materials including but not limited to foam and silicone. In addition to having the ability to deform softly, it can also prevent the induction conduction component 21 from falling off by mistake. In this way, when the user presses the sensing key 20 with the finger 3 to press against the touch button 2, both the elastic extension ring piece 15 and the gasket 22 can elastically deform in response to the pressure change. By providing the induction conduction component 21 in the sensing key 20, the touch signal and the pressure value can be transmitted to the touch button 2, and the touch button 2 can sense the length, strength, and magnitude of the user's pressing time to trigger the operation function. In a preferred embodiment of the present utility model, the conduction parts 211 are arranged in an equidistant line and evenly distributed on the induction conduction component 21, so that when the finger 3 touches any position on the surface of the covering piece 24, the touch signal can be conducted to one end of at least one conduction part 211. In this way, the touch signal of the finger 3 can be transmitted to the touch button 2.

[0025] As Figure 5 shown, when the finger 3 presses the sensing key 20, the elastic extension ring piece 15 and the gasket 22 deform, causing the induction conduction component 21 to sink, and one end of the induction conduction component 21 touches the touch button 2. The pressure applied by the finger 3 can be directly transmitted to the touch button 2 through the induction conduction component 21. Since the induction conduction component 21 is made of non-elastic deformation material, the pressing force can be accurately transmitted, achieving the purpose of easy operation.

[0026] Furthermore, as Figure 6As shown, if the touch button 2 is provided on the back of the mobile phone 1 (for example, applied to the focal length adjustment when the camera is enabled), according to the technology of the present utility model, the sensing key 20 can also be provided at the position of the back plate 11 corresponding to the touch button 2.

[0027] The above-described embodiments are merely preferred embodiments given to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present utility model are all within the protection scope of the present utility model. The protection scope of the present utility model is subject to the claims.
